WATERPROOF ELASTIC FABRIC.

Application led October 9,

To all 'whom z't may oon/cem."

v Be it known that I, ARTHUR C. SQUIRES, a citizen of the United States, and resident of College Point, borough vof Queens, county of Queens, and State of New York, have invented certain new and useful improvements in Waterproof Elastic Fabrics, of which the following is a specication.

This invention relates to elastic fabrics, and has for its principal object the provision of a fabric of this character, which shall be Waterproof and have considerable .Y tensile strength so that it may be subjected to use in the presence of moisture without impairing its elasticity.

A further object of this invention is the production of a fabric having the desired elastic, waterproof and wearing qualities, which may be easily and inexpensively manufactured. f

A. further object of the invention is the production of a waterproof elastic tape adapted for use in the bands of bathing caps, and for use in various otherv connections in which the well-known textile-covered elastic tape of commerce has heretofore been employed, and a special object of the invention is to utilize said commercial elastic tape in the manufacture of my improved waterproof elastic fabric.

In the drawing, Figure l is a plan view of a strip of tape from which a portion of the waterproof coating or envelop has been removed; Y

Fig. 2 is a transverse sectional view of the tape; and

Fig. 3 a transverse sectional view of the tape on an enlarged scale.

Referring to the various parts by numerals, l designates a piece of the wellknown elastic tape of commerce, composed of the usual longitudinal rubber threads 2,

incased within the usual woven textile fabric 3 which serves to hold the rubber threads against displacement. 4C designates the waterproof coating or envelop of pure rubber, which completely covers the commercial tape so as to prevent access of moisture thereto.

The rubber coating may be applied to the tape in any suitable manner, such as by rolling pure sheet rubber in a green state on the tape l, by calendering rolls, and subsequently vulcanizing the composite fabric. The rubber coating or envelop completely covers the faces and edges of the tape and adheres thereto, a portion of the rubber being embedded in the interstices of thetape l. The

vulcanization process is carried out in any known manner so as to produce an elastic, vulcanized rubber coating. It will be observed that I have provided an inexpensive and easily manufactured fabric, possessing good wearing qualities and having a foundation of commercial, textile-covered, elastic fabric and a waterproof surface-coating entirely inclosing the foundation fabric to exclude moisture and preserve the elastic qualities of the rubber threads in the foundation fabric, the waterproof coating or envelop being also elastic so that the elastic qualities of the foundation fabric are fully maintained in the composite waterproof fabric What l claim is:

l. A waterproof elastic fabric having rubthreads and textile warp and weft threads, and a surface coating of rubber.

2. An elastic fabric woven with rubber and textile warp threads and 'textile weft threads and having a surface coating of pure rubber vulcanized thereon.

In testimony whereof I hereunto ax my signature.

ARTHUR C. SQUIRES.
